Deploy the reference CHC service

We need to find a place, or make a place, to get this running. It needs to be publicly reachable and ideally run on infrastructure with consistent performance. I.e. not colocated if we can avoid it.

It's just a web service, and it stores its data in memory. So, it doesn't need too much compute. At least that's my expectation. It will be handling requests from a pool of HPs in parallel but I'm thinking it can manage well enough with a couple of cores and lots of threads.
